Application filedi'anuary 18, 1899, Serial No. 702,515. (No model.)

To all whom, t maylconcernj Be it known that I, ROBERT yCUMMING. AN-

' NAND, of Cornwallis street, South Shields,

England, have invented lcertain new and use)y ful Improvements in Toolsfor Setting Fasteners and for Like"` Purposes, of which the following isa specification.

My invention has referenceto j fastening together the ends of tapesinprinting-machines, and comprises a special tool, in

the form of a double-mouthed tongs or pliers, for rapidly and efcientlymaking the connection by means of a particular forni of fastener.

In the accompanyipgwdrawings, Figure 1 is a side elevation', Fig. 2 isan end View, and Fig. 3 is an under side plan, of the fastener, lookingonto thepoin'tsjof the same. Fig. 4 is a sideelevation showing the endsof two tapes joined together with the fastener. Fig.

5 is an under side plan ofV Fig. 4, Fig. G is an elevation of thetongslookingfrom the hammer side. Fig. 7 is an elevation of the tongs, takenat right angles to Fig. 6. Fig. S is an elevation of part of the tongswith the jaws in section, showing the fastener in position in the openinserting-mouth of th'e tongs; Fig. 9 is a similar view showing thetongs closed. Fig; 10 is Van end view of Fig. 9.

Fig. 11 is an elevation of part ofthe tongs,"

showing the fastener ,inserted in the tape ends preparatory to itspoints being clenchedV the fastener for the purpose of enabling it to beheld temporarily in the tongs, as hereinafter described.

Referring now to the double-mouthed tongs, (shown in Figs. 6 to 12,) 4and 5 are two parts or handles pivoted close to each other on a colnmonpivot-pin 6. At'its outer end, beyond the pin 6, thepart 4 is formedwith a jaw 7, and theouter end of the part 5 is formed with a jawBetween the two jaws oining or A nick or notch 3` 7 and 8 thereisarranged a jaw 9, pivoted on the pin 6 by means of two lowerextensions 10 10, situated at the respective outer sides of the jaws 7and 8. One end of the pivot-pin 6 is formed as a hainmelhead 11. Thecoperating surfaces of the jaws 8 and 9 are plain. 'Asmalllever-catch 12is pivoted at 13 in the jaw 7 and is adapted to project, with its catchportion 14, through a slot internally beyond the surface of the jaw 7,in the center line of the latter. A spring 15, fixed to the jaw 7 by ascrew 16, is arranged to press up against the tail portion 17 of thelever 12 and so normally keep the catch 14 in its projecting positionbetween the jaws 7 9. A stud 1S is fixed in thecenter line of the insideface of the jaw 7 at such a distance from the catch 14 that a fastener1, when, placed lengthwise with, the notch 31 Iin one end up `againstthe stud 18, will just clear the catch 14 when the latter is retractedby pressure applied to the tail 17. Then on releasing the tail 17 thecatch 14 will project through the notch 3 in the other end of thefastener and bear upon the fastener, and thus hold it fiat up againstthe inside face of the jaw 7, as shown in Fig. 8. Corresponding recesses19 and 2O are provided in the cooperating face of the jaw 9 to receivethe studi 18 and catch 14 when" the jaws 7 and 9 are closed uponeachother, as shown'in Figs. 6, 9,10, and ll, and more clearly in Fig. 12.In this face there are also formed two deep grooves 2l 21, which extendlongitudinally on either side of the center line of the jaw and whichare spaced apart at their parallel outer parts at a distance equal tothc width of the fastener 1 when held in the jaw 7, so as to receivefreely the two rows of points 2 of the fastener when the jaw 7 is movedtoward the jaw 9. The grooves 21 21 are arranged to converge at theirinner parts to such an extent that on closing'the jaws 7 and 9 togetherthe rows of points 2 of the fastener will be bent inward or toward eachother about thirty degrees from their original perpendicular position.

The mode of using the fastener and the double-mouthed tongs in joiningthe ends 22 23 of a tape is as follows: A fastener 1 is inserted in thetongs in the manner shown in Fig. 8, the fastener being held in positionby the catch 14 and the stop 18 engaging with IOO the notches 3 vin theVendsof the-fastener.

Then the ends 22 23 of the tape to lbe connected, having been broughttogether and placed one upon the other so as to overlap each other tothe required extent, the tongs is held so that the saidoverlapping endsof the tape lie transversely against the face of the jaw 9, so as toexactly face the fastener 1, as shown in Fig. 8. On pressing the handles4 and 5 of the tongs toward each other lthe teeth 2 of the fastener areforced through the tape ends 22 23-and they .pass into the itl-- clinedgrooves 2l 21 in the opposite jaw 9 of the tongs, whereby the two rowsof points 2 of the fastener are bent inward toward each otherfasshownin-Figs. 9 and 10. The tongs is then opened and the fastener, which isnowiirmly through the ends of the tape, is brought between vthe jaws 8and 9, as shown in LFigs. ll and 12,*wherebywhen these jaws areforcedtogether the points 2 of the fastener are'effectually clenched by thepressure ofthe tongs, as shown in Figs. 4 and 5.

The device on the jaw '7 for temporarily saidjaws, and movable into andout'of position'relatively to such jaw,'and when lin position relativelyto such jaw, held `toward it by the-other jaw.

v2. In tools, the combinationwith two opposing jaws, one movable rtowardthe other for acting on an article between them, of an intermediate jaw,between said jaws,fmovA able relatively to both, and "having working Yfaces lon its opposite sides opposed tothe adjacent iaces ofthe outerjaws, and reciprocal thereto.

3. In a tool or device for inserting the teeth of a plate-fastenerthrough the overlapping ends of tapes to be joined in printing machineryand for clenching said teeth after insertion, two outer jaws movabletoward and 'from each other on the same pivot-pin and having handles formoving same in combination witha middle double-faced jaw between saidouter jaws and movable on Isaid pivotpin but not connected to saidhandles, said middle jaw coacting with either of said outer jaws asrequired, substantially as and for the purpose described.

4. In a tool or device'havi'ng'two'outer jaws and a middle double-facedjaw'allpivotedon the same pivot-pin'andtwohandlesfor moving ysaid outerjaws respectively as and for the purpose set forth, means fortemporarily holding a toothed tape-fastening'plate against the innerface of one of said outer jaws and recesses in the coactingface of saidmiddle jaw to receive the fastener-teeth when "the jaws are closed,substantially as'described.

5. In atool'or device having two outer jaws and amiddle double-faced jawall pivoted'on the same pivot-pinand two handles formovingsaid outerjaws respectively as and 'for the purpose Vset forth, a -springscatchanda fixed stud on the inner face of yone of lsaid outer jaws, recessesin the coacting face of said middle jaw corresponding withsaid catch andstud, and Atwo longitudinal grooves in said coacting face of the middlejaW,-saidin ner grooves converging at theirinnerparts, all substantiallyas and for the v*purposedescribed.

In witness whereof I haveliereuntosigned mynamein the presence oftwo-subscribing witnesses. y
